[R] sourcing a linux file with "system"

[james.foadi at diamond.ac.uk]

Dear R community,
I would like to source a file in my linux system to set a few environment variables.
I have tried:

> system("source /home/james/build//ccp4-6.1.13/include/ccp4.setup")

and got:

sh: source: not found

In fact, using Sys.which("source") I get an empty string.
How can I source that ccp4.setup file from within an R session?
